Another one of my old synth demo-tapes from the 80's ..This is Part of the Kurzweil 250 demo-tape "An Introduction to the Kurzweil 250 with the voiceover explaining about Kurzweil Music Systems, technology and the features of the 250.

Porbably the best of any of the synth-demo tapes/cd's I've heard from the 80's and 90's
